Letters Patent No. 83,187, dated October 20, 1868.

IIVIPROVENIENT IN ROTARY CULTIVATOR.

The Schedule referred to in these Letters Patent and making part of thesame.

.taken in the line :t x, fig. 2.

Figure 2, a plane or top view of the same.

Similar letters of reference indicate like parts.

This invention relates to a new and improved device for cultivating theearth, and sowing seed; and it consists of one or more shafts, providedwith teeth, and having a rotary motion communicated to them by theforward motion of the machine, the seed-distributing apparatusbeing'operated from the rotary toothed shaft, and all constructed andarranged substantially as hereinafter fully shown and described.

The invention also consists in a novel application of harrows to themachine, as hereinafter set forth, for harrowing in the seed.

A represents the frame of the machine, to which the draught-pole B isattached. This frame has four pendant inclined pieces a attached to it,between the lower parts of which shafts O are fitted, and allowed toturn freely, there being three shafts in all, and to each shaft O thereare attached teeth b, which are in contact with the ground as themachine is drawn along.

To the outer end of the left-hand shaft C there is attached a crank,D,to which a rod, E, is connected, the front end of said rod beingattached to an arm, c, which projects from a shaft, d, the latter beingconnected by a link, e, with a' bar, EX, which is fitted longi- F, onthe front part of the E has teeth f attached to it, and

at the rear of a slot, g, in the frame A. This bar it is placed directly:front of the hopper, which extends the whole length of the same.

It will be seen that a reciprocating motion is given the bar EX from theroller-shaft C, which has the crank attached to its end, and that theseed is discharged from the hopper, through the slot g, by the reciprofeating movement of the toothed bar EX.

The discharge of seed from the hopper is regulated by a slide, h, whichis attachedto a frame, FX, extending around the hopper, and working onpivots t t', said frame having a lever, G, attached to its rear end, bywhich the slide h maybe readily raised and lowered, to vary the capacityof the slot g, as may be required.

H H represent two harrows, by joints or links j j, to the inclinedpendant bars or pieces a. The barrow-teeth k are inserted in the rear,cross-bars of the harrows, and each harrow is connected, by a chain orcord, l, to a lever, I. These levers are connected to inclined bars J-J,on the rear parts of which the drivers seat, K, is secured. The lever II may be operated by the pose of raising the barrow-teeth when required.

The teeth b serve to pulverize the earth, and perfectly inoorporatetheseed therewith, while the teeth k of the harrows cover the seed.

Thedevice may be used as a cnltivator alone, no seed being placed inthehopper in this case, `andin order to cultivate or lighten up the groundbetween the rows of plants, the centre-shaft O is removed, so that afree, unobstructed space will be allowed for the plants, a shaft, G,with its teeth, working at each side of the row of plants, and a horsewalking in each space, the machine straddling the row, as it is comInonly termed.

Having thus described my invention,

I claim `as neW,. and desire to secure Patentp 1. The rotary toothedshafts O, two or more, in combination-with the reciprocating toothedbar, E, operated om one of the shafts O, substantially as and for thepurpose set forth.

2. The combination of the reciprocating toothed bar E, with the slot g,in the front side of the hopper F, and the .adjustable slide, h,attached to the pivoted frame FX', all arranged substantially in themanner as and for the purpose specified.

3. The harrows BI H, attached by hinges or joints j j, in combinationwith the rotary toothed shafts and the seed-distributing apparatus, allarranged substantially as and for the purpose set forth.
